The site in question is part of the UNESCO World Heritage site 'Swiss Alps Jungfrau-Aletsch'; its description by UNESCO [1] mentions, in part: "It features a wide diversity of ecosystems, including successional stages due particularly to the retreat of glaciers resulting from climate change. The site is of outstanding universal value both for its beauty and for the wealth of information it contains about the formation of mountains and glaciers, as well as ongoing climate change." [1] Not entirely sure how a new dam would be compatible with its heritage designation, but it would certainly continue to illustrate ongoing climate change.
